Whiteline 02-07 Subaru WRX Sedan and Wagon / 03-07 Subaru Impreza Non-Turbo / 04-07 Subaru STi / 93-

If you're working on the suspension of your 1993-2007 Subaru Impreza, WRX, STI, Forester, Legacy, or Saab 9-2X, this Whiteline Control Arm Inner Lock Washer Kit (KCA377) is designed to help you lock down your alignment settings. This kit replaces the stock toe adjustment components, allowing you to precisely set and maintain your desired alignment angles, especially when using aftermarket adjustable control arms.

The design works to improve traction by letting the wheels follow the road surface more closely. This means better grip when you're accelerating, especially through corners, and it helps significantly reduce both understeer and unwanted front wheel spin. The metal parts are treated with protective plating that's tougher than standard paint, offering solid resistance to corrosion and the elements, so they'll hold up even in tough conditions.

An installation guide is included to walk you through the process. This kit is a well-built option for anyone looking to fine-tune their Subaru's handling characteristics.
